[0025] refer to Figures 1 to 3 According to a preferred embodiment of the present application, a gas-liquid separation device that is easy to detect will be described in detail below. The gas-liquid separation device that is easy to detect includes a processing tank 10. The processing tank 10 includes a tank body 11. The tank body 11 is located above a pipeline. A gas-liquid mixture, such as a gas-liquid mixture composed of alkali solution and hydrogen or oxygen, is passed into the pipeline.

[0026] The tank body 11 includes a tank body 111 and two partitions 112. The two partitions 112 are arranged in the tank body 111 at a predetermined height difference to separate the internal space of the tank body 111 into a connecting cavity 1101, a cooling cavity 1102 and a processing cavity 1103. The connecting cavity 1101, the cooling cavity 1102 and the processing cavity 1103 are arranged in sequence from bottom to top. The tank body 111 is located above the pipeline. A connecting port 11101 connected to the connecting cavity 1101 is formed at the bottom of the tank body 111. Part of the gas in the gas-liquid mixture flowing through the pipeline flows into the connecting cavity 1101 through the connecting port 11101.

[0027] The processing tank 10 includes at least one heat exchange tube 12, which is installed in the cooling chamber 1102. The connecting chamber 1101 is connected with the processing chamber 1103 through the heat exchange tube 12. After the gas in the connecting chamber 1101 is introduced into the heat exchange tube 12, it exchanges heat with the cooling medium in the cooling chamber 1102 to reduce the temperature to obtain condensate and pre-deliquesced gas. The condensate flows downward along the inner wall of the heat exchange tube 12 to flow into the connecting chamber 1101. The pre-deliquesced gas is discharged from the heat exchange tube 12 and introduced into the processing chamber 1103.

[0028] Preferably, a plurality of the heat exchange tubes 12 are provided, and the plurality of the heat exchange tubes 12 are arranged at intervals, and the gas in the connecting cavity 1101 is diverted to be introduced into the plurality of the heat exchange tubes 12, so that the overall flow rate of the gas during heat exchange is large enough while improving the heat exchange effect, so as to reduce the liquid content of the obtained primary deliquated gas as much as possible.

[0029] The tank body 111 has a cooling liquid inlet 11102 and a cooling liquid outlet 11103, both of which are in communication with the cooling cavity 1102. The cooling liquid inlet 11102 is disposed at the lower end of the side wall of the tank body 111 forming the cooling cavity 1102, and the cooling liquid outlet 11103 is disposed at the higher end of the side wall of the tank body 111 forming the cooling cavity 1102. The cooling liquid inlet 11102 is used to introduce a cooling medium implemented as a cooling liquid into the cooling cavity 1102, and the cooling liquid outlet 11103 is used to discharge the cooling liquid heated by heat exchange in the cooling cavity 1102.

[0030] Preferably, the cross-sectional dimension of at least part of the lower end of the connecting cavity 1101 in the transverse direction gradually decreases from top to bottom, so that after the condensate flowing downward along at least part of the inner wall of the heat exchange tube 12 drops to the tank body 111 to form the lower end of the inner wall of the connecting cavity 1101, the condensate can be guided to flow quickly toward the connecting port 11101.

[0031] The processing tank 10 includes a polytetrafluoroethylene filter element 13, and the polytetrafluoroethylene filter element 13 is installed in the processing chamber 1103. The top of the tank body 111 forms a gas outlet 11104 connected to the processing chamber 1103. The primary deliquated gas introduced into the processing chamber 1103 is deliquated by the polytetrafluoroethylene filter element 13 to obtain the secondary deliquated gas, and the secondary deliquated gas is discharged from the gas outlet 11104 to be detected as a sample.

[0032] In this way, the gas is fully dehydrated by successively performing cooling and dehydration and filtering and dehydration, so that when the instrument device is used to detect the dehydrated gas in the future, the gaseous liquid and mist in the gas can be effectively prevented from affecting the service life of the instrument device. In addition, the heat exchange tube 12 and the polytetrafluoroethylene filter element 13 are arranged in the tank body 111. Compared with the existing method of successively performing spraying and dehydration, condensation and dehydration, the arrangement of pipelines and the use of components are reduced, and the equipment cost and the use cost are reduced. In addition, the gas phase space is smaller, and the dehydrated gas can quickly flow to the location of the instrument device, and the delay time of data detection is shorter, thereby improving the accuracy of detection.

[0033] It is worth mentioning that the gas-liquid separation device which is easy to detect can be set at any position of the pipeline to increase the convenience of use.

[0034] refer to Figures 2 to 3 The treatment tank 10 includes a plugging assembly 14, and the plugging assembly 14 includes a float 141 and a plugging seat 142. The float 141 and the plugging seat 142 are both arranged in the treatment chamber 1103 and below the polytetrafluoroethylene filter element 13. The plugging seat 142 has a through hole 14201. The float 141 is located below the plugging seat 142 and is configured to be able to move up and down to abut or separate from the plugging seat 142 to plug or open the through hole 14201. There is a gap between the float 141 and the side wall of the tank body 111, and the gravity of the float 141 is greater than the buoyancy applied to it by the initial deliquated gas but less than the buoyancy applied to it by the liquid in the gas-liquid mixture.

[0035] Specifically, after the initial deliquated gas is introduced into the processing chamber 1103 by the heat exchange tube 12, the initial deliquated gas flows through the gap between the float 141 and the side wall of the tank body 111 to the top of the float 141 and is guided to the through hole 14201, and then the polytetrafluoroethylene filter element 13 removes the liquid from it; after the liquid passes through the connecting port 11101 and flows through the connecting chamber 1101 and the heat exchange tube 12 and is introduced into the processing chamber 1103 due to factors such as failure and shutdown, the liquid applies buoyancy to the float 141 to move it up and close to the blocking seat 142, and the float 141 abuts against the blocking seat 142 to block the through hole 14201 to prevent the liquid from flowing above the blocking seat 142, thereby preventing the polytetrafluoroethylene filter element 13 from being immersed in liquid and causing liquid to adhere to its surface to affect subsequent ventilation or being damaged and failed due to hydraulic pressure, thereby protecting the polytetrafluoroethylene filter element 13 and instrument devices.

[0036] The tank body 111 forms at least one limiting portion 1111 on the surrounding side of the float 141, and the limiting portion 1111 is used to limit the horizontal position of the float 141 to guide the float 141 to move up and down, to prevent the float 141 that floats up and abuts against the blocking seat 142 from being misaligned with the through hole 14201, and to ensure that the float 141 can effectively block the through hole 14201.

[0037] Preferably, four limiting portions 1111 are provided, and the four limiting portions 1111 are respectively provided around the floating ball 141 to jointly limit the floating ball 141 in the horizontal direction.

[0038] In one embodiment, one limiting portion 1111 is provided, and the limiting portion 1111 is in a ring shape to surround the floating ball 141 to limit the floating ball 141 in a horizontal direction.

[0039] refer to Figures 2 to 3 The tank body 11 further includes a support member 113, which is located in the processing chamber 1103 and is placed below the float 141. The support member 113 is used to support the float 141. The support member 113 is spaced a predetermined distance from the partition member 112 and the top of the heat exchange tube 12 located above. The support member 113 is formed with a plurality of through holes 11301 in the vertical direction. The pre-deliquified gas introduced into the processing chamber 1103 by the heat exchange tube 12 flows upward through the through holes 11301.

[0040] refer to Figures 2 to 3 The gas-liquid separation device for easy detection further includes a connecting pipe 20, the connecting pipe 20 has a connecting channel 201, the tank body 111 is installed in the radial direction of the connecting pipe 20, and the connecting cavity 1101 is connected with the connecting channel 201 through the connecting port 11101. The connecting pipe 20 is installed on the pipeline, and the gas-liquid mixture passing through the pipeline flows through the connecting channel 201, and part of the gas in the gas-liquid mixture introduced into the connecting channel 201 is guided to the connecting cavity 1101 through the connecting port 11101.

[0041] Preferably, the connecting pipe 20 includes a main body 21 and an expansion part 22, the tank body 111 is installed in the radial direction of the main body 21, the expansion part 22 is formed by extending from one end of the main body 21, and the main body 21 and the expansion part 22 together form at least part of the connecting channel 201. The inner diameter of at least part of the expansion part 22 gradually increases along the flow direction of the gas-liquid mixture. In the process of introducing the gas-liquid mixture into the connecting channel 201, the flow speed of the gas-liquid mixture gradually decreases, and the gas-liquid mixture diffuses in the part of the connecting channel 201 located in the main body 21, so that the amount of gas directed to the connecting port 11101 is increased.

[0042] Preferably, the connecting pipe 20 further comprises a contraction portion 23, which is formed at an end of the main body 21 away from the expansion portion 22, and the main body 21, the expansion portion 22 and the contraction portion 23 together form the connecting channel 201. The inner diameter of at least a part of the contraction portion 23 gradually decreases along the flow direction of the gas-liquid mixture, so that the flow velocity of the gas-liquid mixture through the connecting channel 201 at the contraction portion 23 gradually increases.

[0043] refer to Figures 1 to 3 The gas-liquid separation device that is easy to detect also includes a valve component 30, which is installed at one end of the tank body 111 close to the connecting pipe 20, and the valve component 30 is used to control the gas to be guided to the connecting chamber 1101.

[0044] Preferably, the valve element 30 is implemented as a ball valve.

[0045] The present application also proposes a working method of a gas-liquid separation device that is easy to detect, comprising the following steps: Part of the gas in the gas-liquid mixture flowing through the pipeline is introduced into the connecting cavity 1101 through the connecting port 11101 and then flows into the heat exchange tube 12 from the connecting cavity 1101. The gas in the heat exchange tube 12 exchanges heat with the cooling medium in the cooling cavity 1102 to cool down to obtain condensate and initially deliquesced gas. The condensate flows downward along the inner wall of the heat exchange tube 12 to flow into the connecting cavity 1101. The initially deliquesced gas is discharged from the heat exchange tube 12 and introduced into the processing cavity 1103. The initially deliquesced gas introduced into the processing cavity 1103 is deliquated by the polytetrafluoroethylene filter element 13 to obtain re-deliquesced gas, which is discharged from the gas outlet 11104 to achieve sampling.

[0046] The working method of the gas-liquid separation device that is easy to detect comprises the following steps: The cooling liquid inlet 11102 passes a cooling medium implemented as a cooling liquid into the cooling chamber 1102 to serve as a cold source for heat exchange with the gas in the heat exchange tube 12 , and the cooling liquid outlet 11103 is used to discharge the cooling liquid heated by heat exchange in the cooling chamber 1102 .

[0047] The working method of the gas-liquid separation device that is easy to detect comprises the following steps: When the liquid passes through the connecting port 11101 and flows through the connecting cavity 1101 and the heat exchange tube 12 and is introduced into the processing cavity 1103, the liquid applies buoyancy to the float 141 to make it move up and close to the blocking seat 142. The float 141 abuts against the blocking seat 142 to block the through hole 14201 to prevent the liquid from flowing to the top of the blocking seat 142, thereby preventing the polytetrafluoroethylene filter element 13 from being immersed in liquid and causing liquid to adhere to its surface, affecting subsequent ventilation, or being damaged by hydraulic pressure and thus failing, thereby protecting the polytetrafluoroethylene filter element 13 and instrument components.

The pre-deliquesced gas introduced into the processing cavity is deliquated by the polytetrafluoroethylene filter element to obtain re-deliquesced gas, which is discharged from the gas outlet. When the liquid passes through the communication port and flows through the communication cavity and the heat exchange tube and is introduced into the processing cavity, the liquid applies buoyancy to the float to make it move upward and close to the blocking seat, and the float abuts against the blocking seat to block the through hole.
